Overview
The Rainin L8-10XLS+ is an 8-channel manual pipette engineered for high-precision liquid handling in demanding life science and clinical laboratory environments. Designed around the fundamental principles of positive displacement and air-cushion aspiration/dispensing, it delivers consistent volumetric performance across all eight channels within its 0.5–10 µL range. Its mechanical architecture integrates a low-force piston drive mechanism and optimized spring dynamics to minimize operator effort—particularly critical during repetitive multichannel operations such as ELISA plate filling, PCR setup, or cell culture reagent distribution. The device complies with ISO 8655-2:2022 (volumetric requirements for piston-operated volumetric apparatus) and supports traceable calibration workflows aligned with GLP and GMP documentation standards.
Key Features
- Ergonomic Low-Effort Operation: Features a lightweight polymer housing and reduced plunger activation force (≤1.5 N at full stroke), significantly lowering cumulative musculoskeletal strain during extended use.
- LiteTouch™ (LTS) Tip Technology: Patented LTS system ensures uniform tip attachment and ejection force across all eight channels—eliminating channel-to-channel variability in seal integrity and reducing tip ejection force by up to 65% compared to standard universal-fit systems.
- High-Reproducibility Sealing Mechanism: Dual-stage O-ring design and precision-machined piston assembly maintain consistent air cushion compression, contributing to the stated accuracy and precision specifications across the full volume range.
- Integrated RFID Chip: Embedded ISO/IEC 15693-compliant RFID tag stores unique serial number, service history, calibration dates, and user-defined asset tags—enabling automated logging in LIMS or CMMS platforms without manual entry.
- Adjustable Volume Control: Fine-tuned thumbwheel with tactile feedback and 0.02 µL resolution allows precise setting across the entire 0.5–10 µL span; lockable volume setting prevents accidental adjustment during benchtop transport or storage.
Sample Compatibility & Compliance
The L8-10XLS+ is compatible exclusively with Rainin LTS-certified tips—ensuring dimensional consistency, leak-free seals, and optimal tip ejection behavior. It is validated for aqueous solutions, buffered saline, ethanol-diluted reagents, and low-viscosity cell culture media (up to 10 cP). Not recommended for viscous, volatile, or corrosive liquids (e.g., concentrated acids, DMSO >20%, glycerol >30%). Regulatory alignment includes compliance with ISO 8655-2:2022 for metrological performance, IEC 61326-1:2013 for electromagnetic compatibility, and RoHS 2011/65/EU for hazardous substance restrictions. The RFID functionality supports audit readiness for FDA 21 CFR Part 11-compliant environments when paired with validated software interfaces.
Software & Data Management
While the L8-10XLS+ operates manually, its embedded RFID enables seamless integration into digital lab infrastructure. When scanned using Rainin’s ProCal Connect mobile app or third-party RFID readers compliant with ISO/IEC 15693, the device automatically populates calibration logs, maintenance schedules, and instrument assignment records in enterprise LIMS or asset tracking databases. Audit trails generated include timestamped calibration events, technician ID, environmental conditions (if logged), and pass/fail status against ISO 8655 tolerance limits. No proprietary desktop software is required for basic operation or RFID interrogation.
Applications
- High-throughput assay setup (e.g., 96-well and 384-well microplates for immunoassays and kinase profiling)
- Genomic workflows including qPCR master mix preparation and NGS library normalization
- Cell-based screening requiring parallel dispensing of growth factors or inhibitors
- Quality control testing in pharmaceutical manufacturing where volumetric traceability is mandated per USP and Annex 15
- Academic research labs prioritizing inter-operator reproducibility and long-term instrument lifecycle management
FAQ
Is the L8-10XLS+ compatible with non-LTS tips?
No. Use of non-LTS tips compromises seal integrity, accuracy, and tip ejection reliability—and voids factory calibration certification.
What calibration frequency is recommended?
Rainin recommends verification every 3 months for routine use, or before critical experiments; full recalibration annually or after mechanical impact, per ISO/IEC 17025-accredited service providers.
Can the RFID chip be rewritten or reprogrammed?
Yes—authorized service centers may update calibration metadata and ownership fields via Rainin-certified RFID programming tools; end users cannot modify core identification data.
Does this pipette require routine lubrication?
No. The sealed piston assembly uses dry-film lubrication and requires no user-maintained greasing throughout its rated service life of ≥100,000 cycles.
How is temperature variation accounted for in accuracy specifications?
All stated accuracy and precision values are validated at 20–25 °C ambient temperature with water at 20 °C, per ISO 8655-2:2022 conditioning requirements; deviations outside this range must be corrected using manufacturer-provided temperature compensation tables.
